What are the waterproof sheets
The main types of waterproof boards include: PVC board, anti-fold special board, color steel plate, EVA waterproof board and XPS extruded board
1. PVC board
PVC is the most common material in plastics on the market, and the PVC board is made of PVC as a raw material with a honeycomb mesh structure in cross section. This kind of board is light in texture and lower in price compared to wood, and can prevent moth, heat preservation and waterproofing. , Is a waterproof sheet with a very high appearance rate. PVC plastic does not absorb water. This is a household knowledge, and it is also the basic principle of PVC water waterproofing.
2. Anti-fold special board
Anti-Better board is a melamine resin-coated composite board, the middle is made of phenolic resin kraft paper pressed at high temperature, which has high durability and water resistance.
The surface layer of the anti-fold special board adopts a special technology of integrated coloring number fat decorative board not only to resist general water splashes, but also to keep the interior dry in a humid environment, and it will not affect the internal materials to cause mold or mold. corrosion.
In addition, it also has super-clean self-cleaning ability. It is difficult to adhere to ordinary stolen goods. The more amazing thing about this kind of anti-fold special board is that it can even be washed directly with water.
3. Color steel plate
Color steel plate, also called color-coated steel plate, is to add a layer of organic coating on the steel plate to achieve the effect of waterproof and corrosion resistance. The color steel plates that we often see in our lives are the roofs of slab houses. They are directly exposed to the outside and will not rust even in the rainy season.
The special coating on the outside of the color steel is composed of silicon-modified polyester or vinylidene fluoride and plastisol. It is very durable. The shelf life is generally 10 to 15 years, and it only needs to be painted every 10 times. Then the average life span can reach more than 35 years.
4. EVA waterproof board
EVA waterproof sheet is also one of the important waterproof sheets. In fact, EVA is already very common in life. Friends who pay attention to the details may find that most of the sneakers we wear on our feet are EVA soles, which are very light, wear-resistant, corrosion-resistant, waterproof, and have a cushioning effect.
The board made of EVA hot-melt adhesive also has the same characteristics, is light and waterproof, the price is not high, and it also has heat insulation properties.
5. XPS extruded board
XPS extruded board is an extruded polystyrene insulation board, which is the third generation of rigid foam insulation material. It uses polystyrene resin as raw material plus other raw materials and poly inclusions, and is heated by a special process Mixing and injecting catalyst at the same time, and then continuously extruding and extruding the molded rigid foam plastic board.
Its biggest feature is its high-strength compression resistance and good heat preservation. Because the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable and there are no gaps, which can solve the problem of water leakage, penetration, frosting, and frosting. Condensation and other issues.
